These things are by definition 70 years old.  Time to open it up, clean, and re-grease.

cut the old rubber tube off.  Remove the cylinder block.  Rotate the gear box until you get access to the two very short screws under the worm shaft.  They release the worm and housing.  Then take those top screws out for access to the ball bearings.

clean, lube, and re-assemble.  Use Toyota #0 hose.

Note that these are good gearboxes, but they can be assembled without proper gear mesh.  Use care to get that worm housing all the way down against the gear housing before tightening the last two screws.
